I bought it out of the blue as a thing to help me learn a little more about rebreathers. I just can't justify the cost of the RB80 at this stage as I don't really need one. I have twin 18's which I can do any dive with and about 10 stages.
I think in the next couple of years, the GUE lads will have something else anyway, so no point working up to something that may change. The RB80 is a good workhorse for those type of dives in the WKPP etc, but I'll never get to do those type of dives, so I may as well buy something cheaper and learn on that.
In time, no doubt, I'll go fully closed. The JJ-CCR looks nice but I just don't know enough about RB's yet to buy one - oh an expensive one.
The X-Link has been discontinued, but I should be able to find one around somewhere.
I would catch a lift with Harvs but he has to go there first.

PH, you are funny. DT is diving tactics of course, but you knew that.
Don't know about the Predator.
It cost me $2k landed, training with JDZ through IART and I don't know what it is like to breathe yet, I haven't got any kitty litter as it only arrived yesterday.
